Synapse not starting tried everything in the faq

So Synapse is not starting or updating on my machine. I've tried to follow the directions on the Support Faq and done everything except uninstalling it and reinstalling it, and I have actually tried to do the uninstall/reinstall however the uninstall stops at 19% and will not continue even if my computer is left on overnight. I tried opening a support ticket and when I clicked the button to submit I got a network error. Here's the event log.

Service cannot be started. SimpleInjector.ActivationException: The constructor of type FeatureManager contains the parameter with name 'logger' and type ITextLogger that is not registered. Please ensure ITextLogger is registered, or change the constructor of FeatureManager.
